WASH-SOLUTION COLLECTOR.

To all whom it may concern:

Be 1t known that I, FRANK GARDNER BECK, a citizen of the United States of America, and resident of Colorado Springs El Paso county, Colorado, haveinvented a certain new and useful Improvement in Wash-Solution Collectors, of which the following is a specification.

My invention relates to wash solution collectors and is for the purpose of gathering any surplus water or'solution which it is desired to take away from any kind of-pulp so that the pulp can be delivered asdry as possible in one place and the solution in another. I

My invention is particularly adapted for use in connection with a revolving drum filter. Such filters are extensively used in the milling industry for the purpose of separat ing precious metal bearing solution from powdered ore. In order to thoroughly accomplish this separation it is necessary to apply to the surface of the revolving drum an excess of wash solution thereby insuring a complete covering of the cake of powdered ore adhering to the surface of the revolving drum. This wash solution'may be water or a solution free from precious metals and by an excess of Wash solution I mean more solution than is needed ;to thoroughly displace the precious metal bearing solution contained in the cake ,of powdered ore adherrin to the surface of the revolving drum. "This drum is artly submerged in a pulp tank which tan contains the powdered ore with the precious metal bearing solution. Heretofore the excess solution, not being used} in the displacement of the precious metal bearing solution contained in the cake of powdered ore, ran 01f the revolving drum into the phlp tank thereby diluting the contents off llhlS tank and thus lowering the if the same. In order to avoid this wash solu' fion from running down into the pulp tank; by Ithe'applicatiou of my wash solution olallectoini Difiiculty was experienced in cti'llecting this excess without injuring the cake but I overcame this'diiiiculty by the prlovision of a soft flexible lipped trough which is adapted to bear on the cake and preveats the excess wash solution from; runnmg dbwn into the trough.

Specification of Letters Patent.

Application filed September 18, 1911. Serial No. 649,861.

My invention will be more readily understood by having reference to the accompanying drawings in which- Figure 1 is a side elevation of a revolving drum filter showing my wash solution collector attached thereto. Fig. 2 is a side elevation of the same. Fig. 3 is a detail view.

I have illustrated my invention in connection with a revolving drum filter which can be of any suitable construction. As shown it comprises a revolving drum 4 sup ported upon and revolving in the pulp tank -Means are provided for creating a suction on the surface of the drum in the well known manner. As filters of this type are well known it is not thought necessary to show or describe the same further in detail.

As the drum revolves in the direction indicated by the arrow through the ore bearing solution within the pulp tank, the powdered ore forms as a cake upon the surface of the drum l as shown at G.

In order to' more thoroughly separate the precious metal bearing solution from the powdered ore an excess of wash solution. is applied to the surface of the cake in any suitable manner for instance by means of the supply pipe 7 Supported upon the tank 5 there is a trough 8 provided with a suitable drain pipe This trough is provided with an upwardly extending portion 10 which lies adjacent to the upwardly moving surface of the drum at. Mounted upon this extension is a soft flexible lip 11 which bears against the surface of the cake. This lip can be made of rubber or any other soft flexible material and possesses sufiicient elasticity so that it bears against the surface of the cake 6 or the drum 5 with sufficient pressure to thoroughly. drain allof the excess solution from the cake into.the trough 8 and thus prevent this excess from passing into the tank and thereby diluting the solution therein. Furthermore this lip being soft and flexible the cake 6 is not injured in any way.

\Vhilc I have illustrated and described my inventiomwith' particular reference to the separation and collection of the excess solution from a revolving drum filter it is to be understood that I do not wish to limit myself to such use but that my invention may be employed whenever it is desired to gather any surplus Water or solution which is desired to be taken zEWay from any kind of moving any excess of said solution, Without 10 111p. injuring the surface of the cake:
